COMBINED VViNDOW-SCREEN AND VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 338,278, dated March23,1886.

Application tiled August 6, 1885.

.To all whom, t may concern:

Beit known that I, HOSEA XV. LIBBEY, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented a new and useful Improvement in a Combined Vindow-Screenand Ventilator, of which the following is a specieation. y

The object of my invention is to provide a window-screen and ventilatorparticularly ap plicable for steam-ears, by means of which fresh air isadmitted into the ear, while dust, smoke, die., are excluded, and thatwithout materially interfering with the view.

The invention consists of a suitable frame adapted 'to fit into thewindow-opening and divided into sections, one or more of which arefitted with glass, and the others with a double wire gauze or nettingwith a layer or thickness of sponge or other suitable absorbent materialbetween,one ofthe wire-gauze sides being provided with pins for holdingthe sponge and made removable, so that it with the `sponge can beremoved for being cleansed and readily Referring to the accompanyingdrawings, Figure 1 is a longitudinal vertical section of a portion of asteam-car fitted with my inveu tion. Figs. 2 to 5 are views showingframes with various arrangements of the glass and wire-gauze, anelevation, vertical and longitudinal section, of each being shown. Figs.6 and 7 are respectively elevation and a vertical section of a portionof the frame and wiregauze provided with pins.

A represents a portion of a steam-ear, and B the windows.

C G are light wooden frames made to iit into the opening between thewindow-sill and the lower part of the sash when the latter is raised.4The frames are fitted at each end with suitable packing, a, preferablyof small rubber tubing, so that when placed in position the tubing willexpand and iill out the groove in which the sash slides and prevent anydust or smoke from entering.

Each of the frames C is divided into sections by cross-bars b, one ormore of these seetions being iitted with glass l), and the othersections being covered on their outer sides by wire gauze or netting E,secured to the frame Serial No. 173,701. (No model.)

G and to erossbars b. The inner sides of these sections are closed bywire gauze or netting E', secured to light frames F, that are held ontothe frames C by means of buttons, bolts, or other suitable fastening,and the inner side of the netting Eis provided with a series of pins,j", (seeFigs. G and 7 on whichis placed sponge or other suitableabsorbent lmaterial, G, preferably cut into layers oftherequiredithickness.

Vhen required for use, the sponge or other suitable absorbent materialis moistened with water and the frame inserted into the windowopening,the sash being drawn down to rest on the top of the frame A. Air willthen percolate through the wire gauze or netting and through the spongeor other absorbent material, which being wet will arrest all smoke,dust, dirt, die., thereby keeping the car supplied with clean fresh air,while the glass D admits of an uninterrupted view.

Then required for ventilation only-such as in the monitor-top H, orbeneath the windows-the frames C may be covered on both sides entirelywith wire-gauze and the whole space between be filled with sponge orother suitable absorbent material, and they may be made to slide insuitable grooves or otherwise secured, so that they can be readilyremoved to be cleansed and replaced again; or they may be secured on theoutside of the car and the openings on the inside of the car covered byregisters, so that air may be admitted or shut out, as desired.

In Figs. 2, 3, andetl have shown the frames G as being fiat with thecross-bars b arranged in different ways, and in Fig. 5 I have shown theframe in the form of a bay, so that the eentral portion will proj eet ash ort distance from the side of the car, thereby causing the sides tobe at an angle, and when the carisin motion the wind will strike againstand percolate through the forward side of the frame, thus giving agreater supply of fresh air.

The bay shown in Fig. 5 may be invertedthat is, made to project slightlyinto the earin which case the wind will strike and enter at the rearside of the frame.

It will be seen that by having the wire gauze or netting E' secured tothe frame F it can be taken out of the main frame and with it the spongeor other absorbent material held by ICO with pins f, for holding spongeor other suitable absorbent material, in combination with a frame havingone side coveredwith Wire I5 gauze or netting, substantially as shown,and for the purpose described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
